ROTARY GAS-ENGINE.

Specification of Letters Patent.

Application filed December 7, 1917. Serial No. 208,011.

To all whom it may concern.-

Be it known that I, Gsonon B. Anna, a

citizen of the United States, residin at Cranberr Lake, in the county of St. Eawrence ant State of New York, have invented new and useful Improvements in Rotary Gas-Engines, of which the following is a specification. v This invention relates to motors and alms to provide a rotary internal combustion motor in which vibration has been reduced, construction simplified, exhaust noises eliminated and all cams and springs dispensed with.

More specifically stated, the invention provides 'a novel form of stationary casing, which permits of the circulation of air to cool the motor, said casing housing therein a revolvin casing in which the cylinders are formet, a frame interposed between the stationary and revolving casings carrying the gearing by means of which the last men tioned casing is operated.

The invention also consists of a novel form of timing device by means of which the ignition spark may be regulated to control the speed of the motor.

The invention further consists of a novel form of packing means employed to increase the compression of the charge within the cylinders.

Further objects and advantages of the in vention will appear when the following description is read in connection with the accompanying drawings, in wh ch- Figure 1 is a side elevation of a motor embodying the present invention;

Fig. 2 is an end view thereof;

Fig. 3 is a view looking at the outside end of the motor from that shown in Fig. 2 with the head plate removed;

Fig. 4 is a vertical sectional view of the same;

Fig. 5 is a similar view on the line 5-5 of Fig. 4:; and

Fig. 6 is an elevation with the outer cas ing broken away to show the packing strips.

Referring to the drawings in detail, similar characters of reference denote corresponding parts throughout the several views.

ned 25, fuel bein eludes the cylindrical portion 12 and the opposite head plates 13 and 14, these head plates being bolted to the cylindrical portlon 12 as shown. Formed integral therewith or secured to each of the head lates 13 and 14 is a bearing 15, Within whlch is mounted the shaft 16.

Mounted to revolve within'the outer casing 10 is an inner casing 17 which includes a plurality of diametrically arranged cylinders 18. These cylinders have their outer ends formed by the casing '10, their inner ends communicating with the crank case 19, within which is adapted to be pieced a lubrieating oil, as is usual. with meters of this type. In order to form a tight joint between the inner and outer casings, so as to hold the compression within the cylinders'lS, there is provided packin strips 20 arranged around the periphery o the cylinder 17 in the form of rings, transversely arranged strips 21 also being carried by the casing l'f, which latter strips intersect thestrips 20.

Mounted for movement within each of the cylinders'18 is a iston 22, the rod 23 of which is connected to one of a number of diametrically arranged cranks 24'formed on the shaft 16, this shaft constituting a crank V for the motor.

The cylinders 18 are arranged in pairs,

each pair being offset from the other, so that they will revolve to pass the cap of the spark plug (hereinafter referred to) at the same relative distance. .The connecting rods" 23 of the pistons are also offset, permittin of a more compact form of construction would otherwise be possible.

Formed in the casing 10 is an intake chansupplied to this channel from any suitab e means through the entrance 26, the inner end of the channel 25 terminating in an intake port 27, which is adapted to alternately communicate with each of the cylinders 18 in their travel within the casing 10. Located upon the opposite side of the casing .10 is an outlet ort 28, which is also adapted to alternatey communicate with each of the cylinders 18.

Located within the top of the casin 1 0 and in the path of the cylinders 18 1s a t on;

Patented Sept. 9, 1919.

common ignition element, in the form of a spark plug 29, controlled by a timing device to be hereinafter explained. carried by the casing 10 is a second spark plug 30 which, as will "be hereinafter explained,

forms a' part of the ignition systemof the motor and is regulated by the timing device just referred to.

A crank shaft 16 is secured to a gear 40, which is adapted to rotate therewith and carried by the outer stationary casing 10 and disposed automatically upon each side of the gear 40 are pinions 4.1 and 4:2. The pinions 42 engage the gear'40 while the pinions 41 engage an internal ring gear 43 secured to the inner casing 17 This causing the inner casing which carries the cylinders 18, to revolve in the same direction as the crank shaft.

In the operation of the motor fuel is drawn into one of the cylinders 18 during its passage over the intake port 27, the piston 22 being then traveling inward, the said piston being at the limit of its inward stroke when the cylinders 18 are in a substantially horizontal position. Further traveling of the cylinder in a clockwise direction will compress the charge, compression beginning as soon as the cylinder passes the horizontal. When the cylinders reach a substantially vertical position, the )istons are at the limit of their outward stro ke and the charge is at the hi best point of compression. The spark pug 29 is located at this point, so that if desired the charge may be ignited at this stage of compression.

As before stated, the invention provides 7 novel means for timing the spark, so that if It is believed that from the foregoing description when read in connection with the accompanying drawings, the construction, operation and advantages of the invention will be apparent. The right is reserved to make such changes in the form and proportion thereof as will fall within the scope of the claim hereto appended.

Having described the invention, what is claimed is:

A motor embodying a stationary cylindrical casing, a cylindrical casing mounted to revolve and having a working fit within the stationary casing, a plurality of diametrically disposed offset cylinders having their outer ends connected to and extending inward from the revolving casing, a common intake port, a common exhaust port, pistons mounted for operation within said cylinders, a single concentrically mounted crank shaft connected to all of said pistons, a concentrically arranged cylindrical casing spaced from the revolvin casing and connecting the inner ends 0 the cylinders to provide a crank casing and a bearing for the crank shaft, and gearing connected to said crank shaft and stationary casing for revolving the cylinder.

In testimony whereof I ailiX my signature.

GEORGE B. ABER.
